Abstract

Background and Objective: Chicory (Cichorium intybus L.) is perennial plants belong to the Asteraceae family. Chicory root can be forced in the dark for producing chicon as a vegetable crop. Also chicory roots have been reported to be the most abundant source of inulin and other oligofructoses.
Materials and Methods: in this experiment the effect of two factors including four plant densities (12, 17, 25 and 50 plants/ m2) and two cultivars (Pagana, Yellow star) with three replications were evaluated based on the randomised complete block design. The experiment was conducted during 2018 in Khalat Pushan Agricultural Research Station (KPARS), University of Tabriz. In the growth period the chlorophyll index were assessed. After harvest the root yield recorded based on the yield of mean row with length of 1.5 m in each plot. in addition to root yield the foliage and root dry weight, root: foliage ratio and inulin content of roots via the colorimetric methods were assessed.
Results: the yellow star cultivar had the higher chlorophyll index and also roots: leaf ratio than Pagana. while about leaf and root dry weight yields, there were no significant differences between two cultivars. Results showed that plant density and cultivar had not any significant effect on inulin content in chicory roots.
